The invention relates to indoles of general formula (I) ##STR1## wherein R.sub.0 represents a hydrogen atom or a C.sub.1-3 alkyl group; R.sub.1 represents a group R.sub.4 CONH--, R.sub.4 R.sub.5 NSO.sub.2 --, R.sub.4 SO.sub.2 NH-- or R.sub.4 R.sub.5 NCO-- (where R.sub.4 is a hydrogen atom or a C.sub.1-6 alkyl group, provided that R.sub.4 does not represent a hydrogen atom when R.sub.1 represents R.sub.4 SO.sub.2 NH--, and R.sub.5 is a hydrogen atom or a C.sub.1-6 alkyl, C.sub.3-7 cycloalkyl, phenyl or phen(C.sub.1-3)alkyl group in which the phenyl ring is optionally substituted by a halogen atom or a C.sub.1-4 alkoxy, hydroxy or C.sub.1-3 alkyl group); R.sub.2 is a hydrogen atom, a C.sub.1-3 alkyl, a C.sub.3-6 alkenyl, a phenyl or a phen(C.sub.1-3)alkyl group; R.sub.3 is a hydrogen atom, a C.sub.1-3 alkyl group or a group --CO.sub.2 R.sub.6, --COR.sub.6, --COCO.sub.2 R.sub.6 or --CONHR.sub. 6 where R.sub.6 is a hydrogen atom or a C.sub.1-4 alkyl, a C.sub.3-7 cycloalkyl, a C.sub.3-6 alkenyl, an aryl or an ar(C.sub.1-4)alkyl group in which the aryl group may be unsubstituted or substituted by a halogen atom or a C.sub.1-4 alkoxy, C.sub.1-4 alkyl or hydroxy group, provided that when R.sub.3 is --CO.sub.2 R.sub.6, R.sub.6 is other than hydrogen; n is zero or an integer from 1 to 5; and pharmaceutically acceptable salts thereof.
本发明涉及一般式(I)的吲哚类化合物,其中R0表示氢原子或C1-3烷基;R1表示R4CONH-、R4R5NSO2-、R4SO2NH-或R4R5NCO-基团(其中R4是氢原子或C1-6烷基,但当R1表示R4SO2NH-时,R4不表示氢原子,而R5是氢原子或C1-6烷基、C3-7环烷基、苯基或苯(C1-3)烷基(其中苯环可以选用卤素原子或C1-4烷氧基、羟基或C1-3烷基取代);R2是氢原子、C1-3烷基、C3-6烯基、苯基或苯(C1-3)烷基;R3是氢原子、C1-3烷基或--CO2R6、--COR6、--COCO2R6或--CONHR6基团,其中R6是氢原子或C1-4烷基、C3-7环烷基、C3-6烯基、芳基或芳(C1-4)烷基(其中芳基可以是未取代或取代的卤素原子或C1-4烷氧基、C1-4烷基或羟基),但当R3为--CO2R6时,R6不是氢原子;n为零或1至5的整数;以及其药学上可接受的盐。
